i need help with the measurements for a sub box so i can fit a kicker L7 15 n a 88 camaro. please help

There's a sticky at the top of the audio section that might help.

It's called 'dimensions well sub box'



I hope the L7 isn't one of those square subs.

yes its the square sub

I've read they are prone to cracking in the corners. Just so you know.

If you like bass, have a look at Fi SSD or Sundown. 15" ARC Audio 'ARC' series work nice as well.
